Abstract—The study is conducted to analyse the efficiency of DC electrical power curve by simulating the different optimum performance of DC electrical motor. The study is accomplished by performing series experiments on DC motor with various current loads and gear ratios and also by constructing the mathematical modelling for the propulsion system data mapping. The outcome of the study shows that DC brushed motor give convincing result on the performance based on power consumption and the completion time. The DC brushed motor was selected based on the results which produce the best configuration for the urban car PEMFC electrical propulsion system.
